new home for older chickens that are not laying

We purchased baby chicks a year ago. a friend gave us 4 Rhode Island reds. I found one of the younger hens pecking a Rhodie until she was bleeding, and her eye was damaged as well. I would like to find a new home for the Rhode island reds. They are not producing eggs, so they are use to us, but I do not want to put them to slaughter. I heard that there is a farm for retired chickens. We live in Massachusetts. Can anyone help? Please? The Rhodies are at least 20 years. Thanks!
